73 duster bellhousing plate

I have a 73 duster with a 360 smallblock and a 727 torqueflite. I am looking for an engine to bellhousing separator plate. There is only one plate listing that shows up on summit racing and online Market places listed as qti-rm-6014 from QuickTime motors. I read that it is 1/8 in thick and I was worried that is not the correct piece. If someone has one for sale or could provide me with the correct part number I would greatly appreciate it
